v4.6.1 is a non-mandatory core release
It contains various bug fixes, GUI improvements, and minor feature improvements developed and tested over the past 2 years.
But there are NO changes to consensus.
For your security, you should always check the binaries against the published file hashes. The list of hashes as well as the source code final commit tag are signed using my GPG key, which you can verify using my GPG Fingerprint posted at https://github.com/hans-schmidt
There is no OSX build due to Apple SDK restrictions, and the windows files are unsigned.
As always, Use at Your Own Risk
